关于冷却考虑在没有空调的情况下千年没有空调，人们在没有空调的情况下生活在炎热的气候中。由于空调使用大量能源，因此在结束后，绿色建筑们应该考虑其他冷却选择，所以房子需要空调。根据美国能源部，三分之二的美国房屋拥有空调系统，其中集体消耗5％的全国各种电力，每年约110亿美元的房主。在该国的部分地区，高温，高湿度或两者都是生命的事实，空调被认为是必要的。然而，有许多方法可以缩小室内空气温度短，安装大型能量密集型空调系统。来自美国能源效率经济委员会的建议：绝缘和收紧。绝缘房屋不需要尽可能多的机械空调，绝缘房屋不佳。会议或超出能源部推荐的绝缘水平是一个很好的第一步。这是在新建建筑中最容易做的，但仍然可行作为改造，特别是在阁楼绝缘时。选择低太阳能增益玻璃窗。 Windows with low solar heat gain coefficients will help lower indoor temperatures and significantly reduce cooling loads. Replace inefficient appliances and products. Replacing old refrigerators with energy-efficient models, exchanging incandescent light bulbs with fluorescents and unplugging electronic equipment when not in use to reduce phantom energy loads all contribute to a cooler interior. Use cool exterior finishes. Light colored roofing and siding can reduce cooling demands by as much as 15%. Keep it shady. Planting deciduous trees and shrubs near south- and west-facing walls can help block intense summer sun. Window shades and horizontal trellises are an option where outdoor plantings are not practical or ineffective. Update existing cooling equipment. If the house already has an…
